Third question...this time serious Sonoff Dongle-E and Zigbee2Mqtt

My first concern is which in fact login and pass should I use in configuration file?

Do you mean the MQTT user and password? That, if you’re using HAOS and the Mosquitto broker add-on, would be the user you created in HA for MQTT.

@mjasinsk

My third concern: It shows me this communicate which actually in other cases is solved by using in config line “adapter: ezsp” which I actually have.

“Zigbee2MQTT:info 2023-11-26 23:14:12: Starting zigbee-herdsman (0.21.0)
Error: Reset error: Error: {“sequence”:-1} after 10000ms
at /app/node_modules/zigbee-herdsman/src/adapter/ezsp/driver/uart.ts:299:23
at Queue.executeNext (/app/node_modules/zigbee-herdsman/src/utils/queue.ts:32:32)”

Well, the problem there is that you don’t have that line - or if you do it’s in the wrong place.

Please post your Z2M config correctly formatted.

@mjasinsk

Ohhhh one more concern…should I disable ZHA in the moment of testing Z2M?

Yes, but be aware that doing this will wipe the stick. You’ll need to ensure you’ve used ZHA’s backup option so you can recover if you want to go back.
